    • Two cooling functions are provided: one being reduction in operation speed of a CPU, and the other being rotation of a motor fan. The two cooling functions are selectively used in accordance with a cooling mode set by a user. When a “Quiet” mode is selected by the user, a mode giving a priority to low power consumption is set to make the battery operation time as long as possible. In this case, the motor fan is not rotated and only the CPU operation speed is lowered. On the other hand, when a “Performance” mode is selected by the user, a mode giving a priority to performance is set. In this case, the CPU operation speed is not lowered, and only the motor fan is rotated. The “Performance” mode and “Quiet” mode can be freely set by the user on a setup screen.
    • 提供两个冷却功能:一个是降低CPU的运行速度,另一个是电机风扇的旋转。 这两个冷却功能根据用户设定的冷却模式选择使用。 当用户选择“安静”模式时,设置优先考虑低功耗的模式,以使电池工作时间尽可能长。 在这种情况下,电机风扇不会旋转,只有CPU运行速度降低。 另一方面,当用户选择“性能”模式时,设置优先考虑性能的模式。 在这种情况下,CPU运行速度不降低,只有电机风扇旋转。 “性能”模式和“安静”模式可以由用户在设置屏幕上自由设置。
